Office Administrator / Customer Success Coordinator

Site Demolition | Sydney, NSW

We’re a growing NSW demolition company looking for an organised, proactive Office Administrator who can also own the customer experience. This role blends everyday admin with customer success — keeping clients informed, supported, and happy from first enquiry through to job completion.

You’ll work closely with the director and operations team, using contemporary tools (including HubSpot) to keep everything running smoothly.

Key responsibilities

- Manage incoming enquiries, emails, and phone calls
- Coordinate quotes, job scheduling, and client communications
- Maintain the CRM (HubSpot) — logging interactions, updating job stages, and following up
- Handle customer success touchpoints: progress updates, issue resolution, and post-job follow-ups
- Prepare and manage documents, compliance paperwork, and basic invoicing support
- Support day-to-day office operations and keep systems organised
- Help improve processes using technology and tools

What we’re looking for





- Experience in office administration, customer service, or customer success
- Comfortable with technology — CRM systems (HubSpot preferred), Microsoft 365, and digital tools
- Strong written and verbal communication skills
- Highly organised, reliable, and able to juggle multiple tasks
- Proactive approach — you spot issues and follow through without being asked
- Experience in construction, trades, or a service-based business is a plus (not essential)

Nice to have

- Previous customer success or account management experience
- Familiarity with HubSpot, quoting systems, or project management tools
- Knowledge of NSW construction compliance or demolition processes

What we offer

- Direct involvement in a growing business
- Opportunity to shape systems and processes
- Supportive, no-nonsense team

If you’re organised, tech-comfortable, and good with people, we’d like to hear from you.
